Chance v. Design Part 4 (Evolution)

Either life came about by a discrete (die roll or coin flip) 'accident' to which all outcomes have an equal chance of being selected, or it is the result of accretion, in which processes of evolution guided these primitive stochastic systems to their ultimate forms via selection, a process that has been well documented and studied. - I must disagree. Life occurred either by design OR by chance. The probabilities that have to be considered in order are: 1)what are the chances for this universe to appear. Penrose calculated an estimate of 10 to the minus 300 prior to the initial conditions, and 10 to the minus 123 if the initial conditions known to cosmologists were present.2) the probabilities of the Earth to be as it is allowing an attempt at life. 3) Going from non-living organic molecules to an organized group of them allowing life. (These have been calculated by legitimate scientists and I'll get the particulars for you.) - What allows natural selection to drive evolution in any direction is competition. Nothing would drive a group of organic molecules, lying around, to do anything. It would take accidental grouping of the molecules, enzymes and the right amount of heat. And then if one could get to an RNAzyme that replicated itself 100% of the time, the show is on. - This is why Shapiro has suggested inorganic cyclical formations. He has worked in this all his life and has nothing to show for it but theories that haven't been tried. You should also read Robert Hazen, working in the field for many years, "Genesis, THe Scientific Quest for Life's Origin", 2005, a history of the failure so far, the absolute failure, since the mid 1950's when the Urey-Miller lightning in a bottle produced 18 amino acids and gunky tar, actually a rather toxic mix. - More later when I look up some material that is not at the tip of my brain or fingers.
